MACHINE FOR ROLLINGANNULAR PLATES.

Specification of Letters Patent.

.To all whom it concern:

Be it known that. we, 'EDWIN I. HnIN-soHN,

- that this disclosure is made, although it will he understood that. the apparatus may be adapted to theforming of annular plates for other purposes.

The invention has for its object toprovide an expeditious and-economical method of and machinefor rolling from the'st-ock,

- which -isxin. the form of'an endless band, preferably'of the desired contour'in' cross section, the beaded annular plates which are used to engage the locking projections or. re-

cesses. on the tire by their head p0rtions,-and provider the necessary inner peripheral web which :abuts the telly of the wheel and through-whi0h the securing bolts on rivets pass.- 7

The object aimed at is accomplished by providing-means, as a pair of rolls, between which the band of stock is drivenand held ,at one point in the circumference ofthe band and during such revolution of the stock, moving it from the plane in which it lies initially. toward a plane at right-anglesto the .plane of its initial revolution.

' In order that the invention may be clear to those skilled in; the art we have: illustrated' in the accompanying drawings one embodiment of our invention, although it will be understood that this showing is merely illustrative and not restrictive of theinvention, which may be worked 'out in other ways andby equivalent mechanical devices.-

Fig. 2 is a plan view ofthe machine shown in Fig; 1.

Fig. 3 is-a view somewhat diagrammatic to show the adaptation of the macl ine to plain stock. Fig. 4 is a detail showing in cross section the appearance of the band as the latter is, operated upon by.

the rolls, and before the bandsupport is turnedior swung upwardly from its original position, Fig. 5 is a'detail showing in cross sectionone ofthe adjustable bearings upon which the band support is journaled. Fig. 6 is a plan view of an adjustable pedestal forming a part ofeach bearing. Fig. 7 is a detail showing in cross section'a specimen of the completed article made by our apparatusL a Referring .to the drawings 'by 'numerals,

-chine bedghaving-a power shaft and drive ried by spindles la, the roll 12. being di- 1 rect-ly driven while the roll 13 is in gear therewith between suitable gears 15 (see dotted lines, Fig. 1),- so as togiveituniform peripheral speed and proper direction of rotation.

The roll 12 is mounted on a flxedportion of the bed 10,-asuitahle yoke 16 being provided for the'upper end-of the spindle. The roll 13 is similarlyinounted'and carried-by a movahle slide 17 traversing suitable ways in the machine bed, the movements of the slide 17 beingeflected by means of a hydraulic'jack or plunger 18 ofanysuitable type and provi'ded' withvthe usual feed and reverse controlling devices, the reversing head of this jack 18 being connected byr-suit able thrust rods 19 witht-he slide 17.- Hinged to-the bed 10 and; in alinement with the bite ofthe rolls l2 and13, isa stock-supporting table 2-0, the. arms of the table straddling the roll 12,- as shown, and being pivoted toisuit able eyes 21 adjustahlv mounted .inI-stapdards' carried by-aan, adjustable supporting block 22 secured to the bed of the machine. This table, as will be seen from Fig. 1, may

' be swung from the full-line position to the dotted-line position through the medium of a suitable hoist, and though any'type of table-elevatingdevice may be utilized, we have found a simple v and eflicient one to be a cable 23, running from an eye at the end oft-he table 20 over pulleys 24,- carried by suitable uprights and thence to a winding drum secured at the end of themachine bed, said winding drum being driven by a counter shaft 26, connected in any suitable manner with the main power shaft and provided with, clutching and unclutching devices, so that the drum. may be thrown into and out of operation as is customary in winding drums.

a 'W th a machine constructed as des cribed,

its operation and the method of forming the annular plates is as :tollows: The roll. 18 having'been retracted by means of the 'hy draulic jack, .the s o'cln.wliicli in'the form shown is an endless hoop or band, is dropped between the rolls, whereupon the roll 13 is brought-up to close position and grips-the band The pdwer being then thrown on,

the band will be revolved between the grip rolls, and the winding drum being- P g started, the table 20 will be gradually moved toward a plane at right angles" to the initial plane of revolution of the hoop. The result of these two movements of the band is to roll it at the point where it is gripped in the rolls from the band-like form of the stock to the annular ring of the finished product, the operation being rapid and effected without deterioration of the material.'

It will be understood, of course, that the shape of therolls can be varied at will according to the cross section of the plate tobe rolled. these rolls being preferably removable from their spindles so that differa roll ent sets of rolls may be employed on the same, machine.

fAs will vbe readily-understood from the foregoing description'. the band resting upon from which the plate is formed is preferably shaped cross section with the beads ribs.

or such other projections as may'be desirable before it is subjected to the rolling operation described to. flatten it into an annular plate and while this is preferable it is not absolutely essential as the stock may, in s0me cases, particularly where the material bein worked is light, be headed or ribbed in this same machine prior to the flattening operation. T It will be obvious that under these conditions a plain, unbead edband, as shown in Fig. 3, would be placed between the forming rolls and revolved between them until brought to the desired formation in cross-section, after which rolling operation the table would be swung to effect the flattening of the band to the ring form, as hereinbefore described.

We claim g 1. Apparatus for forming annular plates, comprising a pair of rolls having operating surfaces of proper width for. engaging the full width of a band as measured in a direction parallel with the general axis thereof,

so as to turn said band peripherally, and means for moving said band toward a plane extending in the general direction of said full width of the band when by said rolls.

2. Apparatus for forming annular plates comprising a pair ofrolls provided with operating surfaces, of proper width to engage the full width of a band as measured in a direction parallel with the general axis of said band. a supporting member for guiding said band relatively to said rolls, and means for normally holding said supthus. engaged portingmember in a predetermined plane ohlioue to the general direction of the grip of the rolls in .order to expand one edge of said band and contract another edge thereof, said supporting member 'being also movable toward aplane extending in thegeneral direction of the width of the portion of the balrlid where the latter is engaged by said ro s.

3. Apparatus for forming annular pla'tes comprising a pair of rolls provided with operating surfaces of proper width to en-. gage the full width of a band as measured in a direction substantially parallel with the general axis thereof. asupporting member disposedjadjacent to said rolls forguiding said band relatively to, the latter; means for normally maintainingsaid supporting.
